As for the Kyun Tou boxing form, there is also a form in Wing Tsun for elbow strike techniques in order to put into practice the various combination options and apply them to combat in a restricted space. To start with, the sand bag is the ideal tool for learning the elbow strike form called Zaang Tou. To do this, the sand bag is grasped firmly in one hand and the free arm delivers the elbow strikes at various heights and in different directions. Subsequently, these same combinations will be put together with the matching form of step sequences. If need be, this learning method can be used in combat, in tandem with sufficient work on movement, to switch easily from the average punching distance to the short elbow strike distance and vice versa.
